Ok, but say you want a Floor Plan and RCP on the same drawing. Draw a base plan which contains the elements that are common to both plans - walls. Insert a door. Now, using WGR & links, set up the drawing to show the door only on the Floor Plan, and the door header only on the RCP.
Classes don't seem to have the necessary level of management tools to separate items per view/sheet/link/whatever.
Or, even if the Floor Plan & RCP are not on the same drawing (which would allow classes to be turned off in the Floor Plan w/o affecting the RCP), HDU draw a door one time, with all the necessary parts (t-hold, door, jamb, swing, header) and control those items separately?
